When you win a game of ranked you get like 1 - 5 elo, when you lose 1 game you lose 30, that is so broken, why do we lose 30 and only gain 1 - 5?
It depends on how the calculations are done. Normal practice is to calculate win and loss points by a comparison between your performance and the average. If you win but don't play well, you will gain fewer points. If you lose badly you will lose more points. Calculations can also depend on the quality of the opposition, so if you're beating up on scrubs, you're not going to reap big rewards.
I have no idea how the calculations actually work in Ironsight, but a combination of these may be the answer.
The calculations are based on your overall performance. When i lose i usually lose around 6 elo
